Hair testing is regarded as a potent method for identifying drug and alcohol consumption. Through the fibrils of a developing hair strand, hair captures biomarkers, offering an extensive history of alcohol and drug use. When cut close to the head, hair provides around a three-month period for detecting alcohol and drugs. It is easy to gather, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's girth) near the scalp delivers 100mg of hair, which is the optimal quantity for testing. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg is advisable. We recommend utilizing a jeweler’s scale for measurement. If head hair is unavailable, the same quantity of body hair might be utilized. Our reference to head hair specifically pertains to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The primary steps in the lab process of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the preliminary handling of a sample within a laboratory setting. This phase ensures the sample was properly sealed and delivered, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody framework.
Screening entails an initial swift assessment for drugs of abuse. Screening offers a cost-efficient method to dismiss drug use in most samples, yet a positive outcome necessitates confirmation for legitimacy in legal settings. Samples that test presumptively positive during Screening necessitate confirmatory steps.
If a sample suggests a positive result during Screening, additional hair is extracted from the initial sample to prepare for Extraction. This phase involves isolating drugs from the hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), illustrating hair drug screening's complexity.
Confirming any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, any presumptive positive samples undergo appropriate cleansing. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair categorization and the adherence to ISO / IEC 17025 standards.
Benefits of hair drug testing:
Drawbacks:
Note: Although commonly termed "hair follicle tests", the test evaluates the hair strand rather than the follicle under the scalp.
